Tree Visualisation and Navigation Clues for Information Visualisation

Information visualisation very often requires good navigation aids on large trees, which represent the underlying abstract information. Using trees for information visualisation requires novel user interface techniques, visual clues, and navigational aids. This paper describes a visual clue for trees as well as an automatic folding (clustering) technique, both based on some mathematical concepts and results in combinatorics. Examples are shown on how these techniques can be used, and what the further challenges in this area are.
